Certificates of survey and plats for tracts of land, filed with the Land Office, for which patents were not issued at that time. A certificate of survey is an official description of a plot of land. The Land Office issued warrants of survey to the county surveyor who then generated certificates of survey. Arranged numerically by certificate number. Indexed by (Certificates and Petitions, Index) in series S25, (Patents, QA, Tract Index) in series S1597, and (Patents, Index) in series S1426. The Archives has created an electronic finding aid from the index in series S1597, supplemented by information from the records themselves. Most documents prior to 1704 were destroyed by a fire in Annapolis. The Land Office received no certificates for unpatentable land in Queen Anne's County between 1827 and 1967. For records after 1967, see (Warrants) in series S1285. The series consists of 333 folders, each containing an average of 3 pages of text and plats.
